RELATED APPLICATIONS

The application claims priority under 35 U.S.C. Section 120 as a continuation of U.S. patent application Ser. No. 12/558,782, filed Sep. 14, 2009, and titled “Content Transfer Involving a Gesture,” Attorney Docket Number 327666.01, the entire disclosure of which is incorporated by reference.

BACKGROUND

Mobile communication devices (e.g., wireless phones) have become an integral part of everyday life. However, the form factor employed by conventional mobile communications devices is typically limited to promote mobility of the device.

For example, the mobile communications device may have a relatively limited amount of display area when compared to a conventional desktop computer, e.g., a PC. Therefore, conventional techniques used to interact with a desktop computer may be inefficient when employed by a mobile communications device. For example, traditional techniques that were used to transfer content typically forced a user to navigate through a series of menus to select content to transfer, select a device to receive the content, and then initiate the transfer. Accordingly, these steps may result in user frustration, especially when transferring multiple items of items of content to different users.

SUMMARY

Content transfer involving a gesture is described. In an implementation, a method is implemented by a mobile communications device that includes recognizing a gesture input via a touchscreen of the mobile communications device that is indicative of a direction, the touchscreen including a display of content. One or more other mobile communications devices are located that are positioned, approximately, along the indicated direction of the gesture. A communication is formed to transfer the content to the located one or more other mobile communications devices.

In an implementation, one or more computer-readable storage media include instructions that are executable by a mobile communications device to determine whether one or more other mobile communications devices are within a predetermined range. If so, data is stored that describes a relative position of the one or more other mobile communications devices in relation to the mobile communications device. The relative position is to be used in determining which of the one or more mobile communications devices are to share content from the mobile communications device in response to a gesture received via the mobile communications device.

In an implementation, a mobile communications device includes a touchscreen having a plurality of edges, a processor, and memory configured to maintain content and an operating system. The operating system is executable on the processor to determine that a gesture received via the touchscreen is indicative of a particular one of four edges of the touchscreen, the gesture being received during display of the content on the touchscreen. The operating system is also executable to determine that one or more other mobile communications devices are positioned, approximately, along the particular edge of the touchscreen. The operating system is further executable to form a communication to wirelessly transfer the content to the located one or more other mobile communications devices.

DETAILED DESCRIPTION

Overview

Mobile communications devices typically have a small form factor to aide mobility of the mobile communications device. For example, the mobile communications device (e.g., a mobile phone) may be configured with a relatively minimal amount of display area and limited input devices (e.g., a keypad) so that the device may be easily transported. Consequently, traditional techniques used to interact with a conventional computer (e.g., a desktop PC) may be frustrating when used in conjunction with a mobile communications device.

For instance, conventional techniques that were used to transfer content may involve multiple steps that are accessed through a series of menus. Consequently, these conventional techniques may be frustrating to users when incorporated by a mobile communications device, especially when transfer of multiple items of content is desired.

In an implementation, content transfer involving a gesture is described. The gesture received by a mobile communications device is indicative of a direction. Additionally, this gesture may be received during output of content, such as during display of an image on the touchscreen such that the gesture also indicates what content is to be transferred.

For example, a “flick” or “drag” may be input via a touchscreen of the mobile communications device during a display of content (e.g., an image) that is directed towards an edge of the touchscreen. The mobile communications device may then determine if one or more other mobile communications devices are located along that edge of the touchscreen, e.g., in the approximate direction of the gesture. If so, content that was concurrently output during the gesture may be transferred to the one or more other mobile communications devices. In this way, a single gesture may be used to select content for transfer and indicate where the content is to be transferred without navigating through multiple menus. A variety of other examples are also contemplated, further discussion of which may be found in relation to the following sections.

In the following discussion, a variety of example implementations of a mobile communications device (e.g., a wireless phone) are described. Additionally, a variety of different functionality that may be employed by the mobile communications device is described for each example, which may be implemented in that example as well as in other described examples. Accordingly, example implementations are illustrated of a few of a variety of contemplated implementations. Further, although a mobile communications device having one or more modules that are configured to provide telephonic functionality are described, a variety of other computing devices are also contemplated, such as personal digital assistants, mobile music players, dedicated messaging devices, portable game devices, netbooks, and so on.

Example Implementations

FIG. 1 is an illustration of an example implementation 100 of a mobile communications device 102 in accordance with one or more embodiments of devices, features, and systems for mobile communications. The mobile communications device 102 is operable to assume a plurality of configurations, examples of which include a configuration as illustrated in FIG. 1 in which the mobile communications device 102 is “open” and a configuration in which the mobile communications device 102 is “closed” as illustrated in FIG. 2.

The mobile communications device 102 is further illustrated as including a first housing 104 and a second housing 106 that are connected via a slide 108 such that the first and second housings 104, 106 may move (e.g., slide) in relation to one another. Although sliding is described, it should be readily apparent that a variety of other movement techniques are also contemplated, e.g., a pivot, a hinge and so on.

The first housing 104 includes a display device 110 that may be used to output a variety of content, such as a caller identification (ID), contacts, images (e.g., photos) as illustrated, email, multimedia messages, Internet browsing, game play, music, video, and so on. In an implementation, the display device 110 is configured to function as an input device by incorporating touchscreen functionality, e.g., through capacitive, surface acoustic wave, resistive, optical, strain gauge, dispersive signals, acoustic pulse, and other touchscreen functionality. The touchscreen functionality (as well as other functionality such as track pads) may be used to detect gestures, further discussion of which may be found in relation to the later figures.

The second housing 106 is illustrated as including a keyboard 112 that may also be used to provide inputs to the mobile communications device 102. Although the keyboard 112 is illustrated as a QWERTY keyboard, a variety of other examples are also contemplated, such as a keyboard that follows a traditional telephone keypad layout (e.g., a twelve key numeric pad found on basic telephones), keyboards configured for other languages (e.g., Cyrillic), and so on.

In the “open” configuration as illustrated in the example implementation 100 of FIG. 1, the first housing 104 is moved (e.g., slid) “away” from the second housing 106 using the slide 108. Other implementations are also contemplated, such as a “clamshell” configuration, “brick” configuration, and so on.

The form factor employed by the mobile communications device 102 may be suitable to support a wide variety of features. For example, the keyboard 112 is illustrated as supporting a QWERTY configuration. This form factor may be convenient to a user to utilize the previously described functionality of the mobile communications device 102, such as to compose texts, play games, check email, “surf' the Internet, provide status messages for a social network, and so on.

The mobile communications device 102 is also illustrated as including a communication module 114. The communication module 114 is representative of functionality of the mobile communications device 102 to communicate via a network 116, such as with another mobile communications device 118. For example, the communication module 114 may include telephone functionality to make and receive telephone calls from the mobile communications device 118. The communication module 114 may also include a variety of other functionality, such as to capture content, form short message service (SMS) text messages, multimedia messaging service (MMS) messages, emails, status updates to be communicated to a social network service, and so on. A variety of other examples are also contemplated, such as blogging, instant messaging, and so on.

The mobile communications device 102 is also illustrated as including a content transfer module 120. The content transfer module 120 is representative of functionality of the mobile communications device 102 to manage a user interface 122 to transfer content 124 to the other mobile communications device 118 via the network 116.

The content transfer module 120 may cause the content to be transferred in a variety of different ways over a variety of networks 116. For example, the content transfer module 120 may communicate directly with the mobile communications device 118 over the network 116, e.g., when configured as a WiFi network or other local wireless network such as Bluetooth. The content transfer module 120 may also communicate the content 124 indirectly over the network 116 when configured as the Internet, such as through a content transfer service 126 implemented using one or more servers 128, further discussion of which may be found in relation to FIG. 3. Thus, a variety of different techniques (e.g., gestures) may be used to initiate transfer of the content 124 to the other mobile communications device 118, further discussion of which may be found in relation to the following figure.

FIG. 2 depicts a system 200 in an example implementation showing a gesture used to initiate a transfer of content 124 from a mobile communications device 102 to the other mobile communications device 118. The mobile communications device 102 as illustrated includes a display device 110 that has four edges that include top and bottom edges 202, 204 and left and right edges 206, 208.

The mobile communications device 102 is also illustrated as receiving a gesture 210 input by a user's finger 212. The gesture 210 may then be recognized as such by the content transfer module 120 using touchscreen functionality. For example, the gesture 210 may be input via a flick or drag of the user's finger 212 across the display device 110 and thus the content transfer module 120 may recognize this gesture 210 and react accordingly. Additionally, the gesture 210 may indicate a relative direction, which in this example is oriented generally towards the top edge 202 of the display device 110.

In response to the gesture, the content transfer module 120 may determine whether another mobile communications device is positioned along the top edge 202 and/or in the indicated direction of the gesture 210. In the illustrated example, the other mobile communications device 118 is positioned both along the top edge 202 of the mobile communications device 102 and in the indicated direction of the gesture 210. Accordingly, content 124 that is displayed on the display device 110 when the gesture 210 is received is then transferred to the other mobile communications device 118.

In the illustrated example, the transfer of the content 124 indicates the direction of the transfer by following the user's finger 212 on the display device 110. The content 124 may also indicate a direction from which it was “received” on the other mobile communications device 118, such as by progressively showing the content 124 as being received from the general direction of the mobile communications device 102 using an animation. Thus, the display of content 124 on the other mobile communications device 124 may indicate a relative location of the mobile communications device 102 that transferred the content 124. A variety of other implementations are also contemplated, such as to display the content 124 on the other mobile communications device 118 when the communication is completed (e.g., the content 124 has completed transfer), and so on.

As previously described, the content 124 may be transferred in a variety of ways. For example, the mobile communications devices 102, 118 may be connected over a local wireless network such that the content 124 is not transferred through an intermediary. In another example, an intermediary (e.g., a web service) is used to transfer the content 124, such as to transfer the content 124 via the internet. In a further example, an intermediary is used to locate other mobile communications devices (e.g., mobile communications device 118) for the transfer (which may or may not be involved in transfer of the actual content 124), further discussion of which may be found in relation to the following figure.

FIG. 3 depicts a system 300 in an example implementation in which the content transfer service 126 of FIG. 1 is used to aid location of the other mobile communications device 118. As previously described, the mobile communications device 102 includes a communication module 114 and a content transfer module 120. In this example, the other mobile communications device 118 also includes a communication module 302 and content transfer module 304 having similar functionality, respectively. Thus, the mobile communications devices 102, 118 are configured to transfer content to and from each other either directly (e.g., over a local wireless connection), indirectly through the content transfer service 126, and/or indirectly through another web service.

The system 300 also includes a content transfer service 126 having a transfer manager module 306. The transfer manager module 306 is representative of functionality to aid content transfer between the mobile communications devices 102, 118. For example, the transfer manager module 306 is illustrated as having a position module 308 that is representative of functionality to track position of the mobile communications devices 102, 118. The position may be tracked in a variety of ways, such as through global positioning data that is obtained from the mobile communications devices 102, 118, indications of locations based on transmitters used to communicate with the devices (e.g., through triangulation), and so on. Thus, the location of the mobile communications device 102, 118 may be determined through communication with the mobile communications device 102, 118 themselves and/or other devices, e.g., cell towers for triangulation.

The position information (and other information) stored by the content transfer service 126 may be used to aid the content transfer process. For instance, the content transfer service 126 may record authentication information of the mobile communications devices, 102, 118 as well as connection information (e.g., a phone number and type of device). The transfer manager module 306 of the content transfer service may then use this information to recognize the devices as an authorized device, and thus a “friend device”.

This information may then be published by the content transfer service 126 to the mobile communications devices 102, 118 at set time intervals. The mobile communications devices 102, 118 may then automatically detect its “friend devices,” such as at predetermined time intervals (e.g., ten seconds) to locate devices within a predetermined range. For example, the range may be set for likelihood of content transfer (e.g., two meters) to limit the number of conflicts between other mobile communications devices, suitability for content transfer (e.g., effective range of a local wireless network), and so on.

For each device that meets these criteria, the mobile communications devices 102, 118 may automatically connect with the found device and record a relative position. The recorded relative position may have the following data structure:

// Relative geo position of a “friend device” Strucut RelativePosition { Public int PhoneNumber; // The number of the phone which is globally unique. Public RelativeSide relativeSide; // Indicate where the “Friend Phone” is currently located Public x,y,z; // relative location in 3D world where the “Friend Phone” is currently located } Enum RelativeSide { Left, Right, Top, Bottom };

Thus, each of the mobile communications devices 102, 118 may record a relative position of other devices that are within range. In an implementation, the devices inform each other when there is a change in position. For example, the mobile communications device 102 may inform the other mobile communications device 118 of a change in coordinates so that the device may update its relative geographic position. This data may also be set to “time out” if updates and/or confirmations of location are not received at predetermined intervals. Therefore, in this example the devices are “aware” of the position of each other before a gesture is received to transfer the content, thereby promoting efficiency in the transfer of the content. A variety of other implementation are also contemplated, such as to locate the devices in response to the gesture. Further discussion of gestures, calculation of relative position, and content transfer may be found in relation to the following procedures.

Example Procedures

The following discussion describes content transfer techniques that may be implemented utilizing the previously described systems and devices. Aspects of each of the procedures may be implemented in hardware, firmware, software, or a combination thereof. The procedures are shown as a set of blocks that specify operations performed by one or more devices and are not necessarily limited to the orders shown for performing the operations by the respective blocks. In portions of the following discussion, reference will be made to the environment 100 and systems 200-300 of FIGS. 1-3, respectively.

FIG. 4 is a flow diagram depicting a procedure in an example implementation in which a relative position of another mobile communications device is calculated and stored for use in content transfer. Data is obtained that describes a location of one or more other mobile communications devices (block 402). For example, the mobile communication device 102 may receive a communication from the other mobile communications device 118 that describes a location of the other device, e.g., coordinates. In another example, this communication may be received from the content transfer service 126, which may have originally received the coordinates from the other mobile communications device 118 and/or determined the coordinates without contacting the device directly (e.g., via cell tower triangulation and so on). In a further example, the data may be obtained from the mobile communications device 102 itself, e.g., using a directional antenna to determine a direction from which a wireless signal was received from the mobile communications device 118. A variety of other examples are also contemplated, such as through location that is assisted by another third-party source, radio frequency identification, and so on.

A relative location of the one or more other mobile communications devices is computed in relation to the mobile communications device (block 404). For example, the content transfer module 120 may obtain the coordinates of the mobile communications device 118 and compare them with the coordinates of the mobile communications device 102 to compute a relative location.

The relative location may be described in a variety of ways. For example, the relative location may be described directionally, such as in a radial manner (e.g., as degrees that follow a basic layout of a compass), generally (e.g., aligned with a top edge, bottom edge, etc.), and so on. In another example, the relative location may be described using relative distances, e.g., close, middle, far. A variety of other examples are also contemplated, such as the storing of actual coordinates which are then used to calculate the relative location at a later time, e.g., after receipt of a gesture.

The relative location is stored on the mobile communications device (block 406). Thus, in this manner the mobile communications device 102 is “ready” for receipt of a gesture to indicate where to transfer the content and can do so in a efficient manner. Additionally, the relative location may be updated on the mobile communications device (block 408). For example, if the mobile communications device 118 is moved, it may communicate an update to the content transfer module 120 of the mobile communications device 102. In another example, the content transfer service 126 and/or the mobile communications device 102 may determine when the other mobile communications device 118 is moved (e.g., through periodic polling) and generate an update. This stored data may then be used to support a content transfer process, further discussion of which may be found in relation to the following figure.

FIG. 5 depicts a procedure 500 in an example implementation in which a gesture is used to initiate a transfer of content to a mobile communications device that is aligned with an approximate direction indicated by the gesture. A gesture input via a touchscreen of the mobile communications device is recognized as being indicative of a direction, the touchscreen including a display of content (block 502). As shown in FIG. 2, for instance, a gesture 210 is received that indicates a top edge 202 of the display device 110. The content transfer module 120 may recognize the gesture 210 and the indicated direction through touchscreen functionality of the display device 110.

One or more other mobile communications devices are located that are positioned, approximately, along the indicated direction of the gesture (block 504). The content transfer module 120, for instance, may query data stored by the procedure 400 of FIG. 4 to determine if one or more mobile communications devices are located along that edge.

A user interface is output that is configured to receive a selection of one or more of the mobile communications devices if a plurality of other mobile communications devices is positioned, approximately, along the indicated direction of the gesture (block 506). For example, a plurality of devices may be located in a direction. Accordingly, in this implementation a user interface is output that is configured to enable a user to select one or more of the devices to receive the content. A variety of other implementations are also contemplated, such as automatic transfer to each friend device in the approximate direction.

A communication is then formed to transfer the content to the located one or more other mobile communications devices (block 508). The communication may be formed in a variety of ways, such as for transfer over a local wireless network, a wide area network, the internet, and so on.

The content is displayed during the transfer to indicate a direction of the transfer (block 510). Referring again to FIG. 2, the content 124 may be displayed by the mobile communications device 102 to be aligned with the indicated direction of the gesture 210 and thus the approximate direction of the transfer. Additionally, the other mobile communications device 118 may also indicate a direction from which the content 124 was received. A variety of other examples are also contemplated.
